Correlation of Acoustic Radiation Force Impulse Imaging with Chronicity Markers in Native Renal Biopsy.

Acoustic Radiation Force Impulse (ARFI) is an ultrasound parameter which has shown promise in assessing liver stiffness, but there are limited data on the correlation of ARFI with chronicity markers in renal biopsies. Determine ARFI values in ultrasound and correlate with chronicity markers in renal biopsy. Determine whether ARFI can be used as a non-invasive chronicity predictor compared to renal length, Resistive Index (RI), and cortical thickness.

Role of Acoustic Radiation Force Impulse Elastography in the Characterization of Focal Solid Hepatic Lesions.

Objective: The purpose of the study is to investigate the usefulness of acoustic radiation force impulse (ARFI) elastography in the characterization of focal solid liver lesions as benign, malignant, or metastatic using ARFI two-dimensional (2D) imaging and ARFI quantification (shear wave velocities [SWVs]).

Materials And Methods: Sixty lesions were included in this study. The lesions were classified into three groups: Group I included benign lesions ( = 25), Group II included malignant lesions ( = 27), and Group III included metastatic lesions ( = 8).
